Quasi-orthogonal intrinsic mode functions
The Hilbert–Huang transform (HHT) is a way to decompose a signal into so-called intrinsic mode functions (IMF) along with a trend, and obtain instantaneous frequency data. It is designed to work well for data that is nonstationary and nonlinear. In contrast to other common transforms like the Fourier transform, … See more Empirical mode decomposition The fundamental part of the HHT is the empirical mode decomposition (EMD) method. Breaking down signals into various components, EMD can be compared with other … See more Chen and Feng [2003] proposed a technique to improve the HHT procedure. The authors noted that the EMD is limited in distinguishing different components in narrow-band signals. … See more • Hilbert transform • Hilbert spectral analysis • Hilbert spectrum • Instantaneous frequency • Multidimensional empirical mode decomposition See more The Intrinsic Mode Function (IMF) amplitude and frequency can vary with time and it must satisfy the rule below: 1.
